Ah, but in reality you are (probably) more likely to stall when when close to MAUW.
I agree that practising this when close to the limits is not the best idea I've ever heard, but if you were uncomfortable about doing these manoeuvers in that machine why not just change a/c?
Being certified for spinning is one thing, but just because the FAA or CAA don't let you spin it on purpose, doesn't mean that the a/c won't spin on its own accord if handled poorly. So if you are to fly that type, then you should learn ALL its foibles and peculiarites such as what it's like in the incipient stage.
If flown correctly, then a full power stall shouldn't lead to a spin, therefore no problem.........
